Quiz - Types of Volcanoes (DOK 1,2)

What is the primary characteristic of the lava from shield volcanoes?

• High viscosity

• Low viscosity

• Sticky and does not flow far

• Forms cinders

Which of the following volcano types is known for being wide and broadly sloping?

• Composite Volcanoes

• Shield Volcanoes

• Cinder Cone Volcanoes

• Stratovolcanoes

Which volcano type is typically not explosive?

• Cinder Cone Volcanoes

• Composite Volcanoes

• Shield Volcanoes

• All of the above

Identify a characteristic that is common to composite volcanoes.

• Quiet, oozing lava

• Alternating eruptions of lava and ash

• Wide and flat

• Forms cinders

Which of the following volcanoes is an example of a composite volcano?

• Mauna Loa

• Skjaldbreiður

• Mt. St. Helens

• Eldfell

What is a common feature of cinder cone volcanoes?

• Tall and pointed

• Wide and flat

• Circular or oval cone

• Broadly sloping

Explain why shield volcanoes are not typically explosive.

• They have high viscosity lava that traps gases.

• They have low viscosity lava that allows gases to escape easily.

• They are formed from alternating layers of lava and ash.

• They are smaller and cannot build up enough pressure.

Compare the slopes of shield volcanoes and composite volcanoes.

• Both have steep slopes.

• Shield volcanoes have steep slopes, while composite volcanoes have gentle slopes.

• Shield volcanoes have gentle slopes, while composite volcanoes have steep slopes.

• Both have gentle slopes.

Why do composite volcanoes often form where two tectonic plates collide?

• The collision creates a flat base for the volcano.

• The collision generates high pressure and heat, leading to explosive eruptions.

• The collision allows for the accumulation of cinders.

• The collision results in low viscosity lava.

Describe the process by which cinder cone volcanoes form their characteristic shape.

• Lava flows far and wide, creating a flat shape.

• Alternating layers of lava and ash build up over time.

• Cinders accumulate around the vent, forming a circular or oval cone.

• High viscosity lava solidifies quickly, creating steep slopes.
